It's broken in Cygwin, at least for 1.3.6-6.  See:

Yes, it fails if auditing is enabled.  Similarly for IRIX 5.3
(IRIX and SunOS share some code in this area, if I recall.)
I vaguely recall it has other NFS-related problems.

It's also missing from Ultrix and AIX 3.2.5.

None of these systems are exactly spring chickens, except for Cygwin.
